Be it known that I, Cuori. M. BrLLiNGs, va citizen of the United Statesof America, and a resident of Brooklyn, county of Kings, and State ofNew York, have inventedcertain new and useful 1improvements in MotorVehicles, of which the following is a vspecification, reference beinghad to the accompanying drawings, forming a part thereof.

My invention relates particularly tothe lighter class of motor vehiclesused forin stance for light delivery purposes.

The objects of the invention primarily are te improve and simplify thespring suspension.

Briefly the invention contemplates the mounting and supporting of theframe or body of the vehicle on leaf springs, having a sliding andpivotal connection with the f axles.

Other features and details of construction will appear as thespecification proceeds and will be understood from the accompanyingdrawings wherein l have illustrated the invention embodied in apractical commercial form.

ln these drawings:

Figure l is a side elevation and part sectional view of the machine.

Figure 2 is a plan view of the chassis, with the motor and control gearomitted. rllhe vehicle disclosed is of the three wheel type, embodyingthe two front steering wheels 5 and the rear drive wheel 6. The frameConsists of the two side sills 7 connected by suitable braces 8 and 9and arranged on rearwardly convergent lines, as indicated in Figure 2.

At the front this frame is supported by the forwardly extending leafsprings l() made fast to the forward ends of the sills at ll, saidsprings having a bearing at their forward ends on the front axle l2.These bearings consist in the present disclosures ef balls or sphericalelements 13, carried by the forward ends of the springs, said ballshaving a rocking engagement in the boxes 14, which are slidably engagedin the casings 15, secured on the axle. The movements of the axlerelative to the frame are controlled by radius rods 16, pivoted to theaxle at l? at points in line with the balls 13 and pivoted at 18 to thebrackets 19 secured to the side sills substantially in line with therearward or fixed ends of the springs. It follows from this constructionthat the axle will have a free up and down movement depend ent upontheflexibility of the spring connections betweeri the axle and frame andcontrolled by the radius rod connections.

' At the rear'the side members of the frame are similarly provided withleaf springs 2O fixed to 'the rearward ends Vof the side sills at'2l andhaving a sliding engagement at their rearward ends in the bearings 22carried by the rear axle which in the casev dis closed takes the form ofthe gear housing 23.

Radius rods 24 pivoted at their forward ends at 24 on brackets in linewith the fixed ends of the springs and pivoted at their rearward ends at25 in line with the axis of the axle control the movements of therearward axle. rihe movement of this axle is further controlled by anadditional set of radius rods 26, pivoted at their rearward ends at 27to the axle housing substantially in line with its axis and pivoted attheir forward ends at 28 substantially in line with the fixed ends ofthe springs. This construction provides in effect a parallel link motionwhich permits the axle housing to rise and fall with respect to theframe while maintaining the. gear casing or housing substantiallyupright.

rlhis gear casing contains suitable gear mechanism which is driven bythe propeller shaft 29, said shaft extending rearwardly. from the motor30. One or more universal joints. such as indicated at 3l and 32 may beinterposed in this drive connection.

The construction disclosed provides a flexible and relatively free formof spring mounting for the body and at the same time the movements areproperly controlled to prevent misalinement of the parts or derangementof the driving and steering gear.

li/Vhat l claim is:

1. ln a vehicle spring suspension, the combination with a vehicle frameand axle housing,of a pair of leaf springs secured .to the llO pivotalengagement with the axle housing and two pairs of pivoted radius rodsextending from the frame to the axle housing with the rods of one pairdisposed in substantial parallelism with the rods of the other pair, onepair of said radius rods extending from substantially' the points` ofconnection of the springs with the frame and connected with the axlehousing at substantially the axis thereof and the other pair `of radiusyrods-extending from a point substantially in line with the points ofconnection of the springs with the fram-e to points `on the axle housingremoved from the axis thereof.

3. In a vehicle spring suspension, the combination with a Vehicle frameVand the front and rear axles, of leaf springs projeeting forwardlyfromthe front ends of the-frame and having `each a sliding pivotalbearing in the front axle and leaf springs projecting rearwardly fromthe rear end of the frame and Vhaving each a sliding pivotal engagementwith the rear axle and radius rods connected between the frame andforward and rear axles for. controlling the relative movements of A.theaxlesvand frame.A

4f. In a vehicle spring; n suspensiom `the combination with a vehicleframe and axle,V

of a box :slidably moiinted .ontlie axle, a spherical bearing,` elementlengaged 1n said slldable box anda leaf spring secured to the frame andengagedv with said sphericalbearingelement.

In witness whereof l hereunto set my day of September, 1919.
